Let's not pretend that using Slow and Para is nothing compared to the T2s. Other jobs can cast them, and a 3 minute ability does not a master Enfeebler make. Did you know RDM has 22 potential debuffs to BLU's 62? Somethin' fishy there.

As for meleeing being a component to your buffs and debuffs... The job is called Dancer. Go ahead and play that if it is the playstyle you are looking for out of your RDM.
You probably ignored my earlier commentary about ideas RDMs proposed years ago actually hitting the game, but not for RDM (Accession/Diffusion/Steps). As is, RDMs and DNCs working together is pretty much impossible for the RDM (Samba/Enspell conflict). Simply telling someone to play another job is being the poster child of closed-minded. Believe it or not, it's possible for RDM to put its own unique spin to things. As is, BLU is a melee mage specializing in spike damage. RDM could be the DoT cousin. We're close, but still need some nudges.
